A laser source includes a first laser device configured to generate a first laser beam having a first wavelength, a second laser device configured to generate a second laser beam having a second wavelength, which is different from the first wavelength, and a non-linear crystal configured to receive simultaneously the first and second laser beams and to generate a third laser beam that has a third wavelength, which is larger than each of the first and second wavelengths. The non-linear crystal has a length and a width, and a variable poling period is distributed across the width so that the third wavelength varies within a given wavelength range based on an incident position of the first and second laser beams along the width of the non-linear crystal.

Tunable mid-infrared laser source and method

A system and method for rapid thermometry using intrapulse spectroscopy can include a laser for propagating pulses of electromagnetic radiation to a region. Each of the pulses can be chirped. The pulses from the region can be detected. An intrapulse absorbance spectrum can be determined from the pulses. An instantaneous temperature of the region based on the intrapulse absorbance spectrum can be determined.

High repetition rate thermometry system and method

A system and method for cavity ring-down spectroscopy can include a pulsed quantum cascade laser, an optical ring-down cavity, a photodetector, and an oscilloscope. The system and method can produce pulse widths of less than 200 ns with bandwidths greater than 300 pm, as well as provide temporal resolution of greater than 10 &#x3bc;s.

Cavity ring-down spectroscopic system and method

An ammonia sensor can include a laser detector configured to provide stable sample readings. The sensor can implement a method including processing the recorded intensity of the laser beam to determine a first harmonic component and a second harmonic component and the amount of ammonia in the sample.
